CVE-2026-67443

FUXA: Unauthenticated guest JWT bypasses Node-RED secure-mode authorization gate (Remote Script Execution)

FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, the allowDashboard authorization gate in server/integrations/node-red/index.js calls authJwt.verify for /nodered without inspecting the decoded identity. When nodeRedEnabled is true, secureEnabled is true, and nodeRedAuthMode is secure, a remote unauthenticated attacker can obtain a signed guest token from POST /api/heartbeat and use it to access the RED.httpAdmin editor and flow deployment API. Because the Node-RED configuration has no second adminAuth gate, the attacker can deploy function nodes or invoke fuxa.runScript and runtime.scriptsMgr.runScript, gaining control of FUXA project data, configuration, scripts, filesystem-capable runtime helpers, and potentially operating-system commands when nodeRedUnsafeModules is enabled. This issue is fixed in version 1.3.3.
